Outlook calendar sync with icloud

Environment : Windows 7, Outlook 2007, iCloud Control Panel 3.1

Goal : I want my outlook calendar to synch with iCloud.com

When I click the Calendar tab in Outlook 2007 I have three different calendars. One is the default "Calender" under a group "My Calendars", and the other two are called "Calendar in iCloud" and "Work in ICloud" that are both under the group "iCloud". It should also be noted that if I log into iCloud.com and go to calendars, I have two calendars there which are called "Calendar" and "Work" (So this lines up with the two I see in Outlook- Great!).

Now what I notice is if I add a appointment to "Calendar in iCloud" then it shows up on iCloud.com and is automatically sync'd to my iphone (Great!). The problem I am having is that when appointments are added in Outlook they are added to my default calendar "Calendar" under "My Calendar". That appointment isnt also automatically copied to my iCloud Calendar and as such it doesn't show up on iCloud.com.

Now I suspect what I am supposed to do is just set the iCloud Calendar as my default calendar in Outlook? I just can't find any settings that will do this. If I copy an appointment from my default work calendar, and paste it in my iCloud Calendar it shows up no problems. But I really don't want to have to manually copy all my appointments over. Shouldn't this be automated? What am I missing here?

Thank you for your time-Joel
